SEPARABLE DOUBLE LETTER-SHEET.

Specification of Letters Patent. A pli ation fil d February 7, 1905.Serial No. 244,548.

; Patented June 25, 1907.

To all whom it may concern:

Be it known that I, MoR'rIMER- A. Hown,

a citizenof the United States, residing at Tacoma, in the county ofPierce and State of Washington, have invented new and usefulImprovements in Se arable Double Letter Sheets, of which the ollowing isa-specification.

My invention relatesto devices for producing and preserving manifoldcopies of thereto, and has for its objects the roviding of a separabledouble letter s eet having four flat surfaces after folding, one of. I

which is to be'used in writing a letter and the surface directlyunderneath and facing the same way is to be usedto receive and hold acarbon copy of the letter written, one of the two remaining surfaces isdesigned to furnish space 11 on which to reply to the letter abovementloned and the surface di- ..rectly underneath thesurface on whichthe Q in separate places and 'valua 1e time is lost.

'1 5s inserted and ready for writing the letter and reply is written,and facing the same way is designed to' receive and hold a carbon copyof the reply, and to rovide a sin le leaf to be inserted between t eleaves of t e separable, double letter sheet which single leaf is de-'signed to receive and hold a carbon copy of the letter; said copy to betemporaril retained as an oflice record until the rep y to the letter isreceived.

Heretofore in keeping a record of letters and the re lies thereto, ithas been the custom to ma e an impression of the letter written upon aleaf in a bound book. This; method is slow and unsatisfactory in thatcopies of the letter and the re ly thereto are in bringing the twotogether whenreference is wanted and for many other reasons too numerousto mention. With my invention these troubles are eliminated: when areply is receivedv it is only necessary to turn the leaf over and readthe record of the original etter.

Certain other minordetails are also emof the second leaf of the lettersheet, also showing the sin le'leaf and carbon sheet inserted and rea yto receive a copy of the letter. Fig. 3 is a pers ective view after theleaves have been folde ten, as referred to in the description of Fig.

. 2, and showing a carbon sheet inserted ready for writing the reply tothe above mentioned on the inner surface of the first leaf.

Similar letters several views. V

A represents that surface of the first leaf upon which the originalletter is. written, B

upon which a carbon copy of the original letter is made, C representsthat surface of the second leaf upon which the reply to the originalletter is written, D re resents that,

surface of the first leaf u on w 'ch a carbon copy of the reply is mae,E represents the carbon sheets used in making the carbon copies abovereferred to, F represents the line at 'or near which they are afterwardseparated, G represents 1:- e porary oflice copy of the letter and Hrepresents the carbon sheet used in making the. carbon copy on thesingle leaf.

The uses to which my invention may be 1 put and the manner of using thesame are as ollows: A. B. G. or any person or company wishing to write aletter to a second erson or com any inserts two carbon sheets and H,amFa single sheet G between the two leaves of the letter sheet, (seeFig. 2) the surface of the carbon sheet E facing the s ace B and thecopying surface of the carbon sheet H facing the single sheet G, the

letter is then written upon the surface A and copied onto the surfaces Band G, the car- .bon sheets E and H and the s' le sheet G are thenremoved and the double etter sheet is then despatched to the personor-company copying the same onto-the inner surface and the letter writ-5 letter and making a carbon copy of the reply refer to similar partsthe represents that surface of the second leaf at which the leaves arefolded together and single leaf or temto Whom the letter is written, thesingle sheet f G being keptas a temporary record pending the recei t ofthe reply to the letter. Upon receipt oftheletter s eet the person orcompany to whom it is written inserts a carbon sheet E, (see Fig. 3) thecopying surface of the carbon sheet E facing the surface D, the personor company then writes a reply to the letter upon the surface 0 andthereply is copied onto the surface D, the carbon sheet is'then removed andthe two leaves-separated at or near the line F and one of the leavesreturned to the writer of the original letter, and the other leafretained by the person or company re lying to theletter.

It is obvious that t e line Fma be perforated or. formed by linesof wealess, or formed by gluing two sheets together, or

formed by merely folding the two leaves to' gether and that it may beplaced at any or all of the four edges of the leaves. It is also obviousthat it may not at all times be necessary to print the letter head orthe preamble tothe reply thereto but blank sheets may be to whichreplies are to be received; in substantiall the same manner as describedregarding etters and the replies thereto.

Having described -my invention, what I claim as new and desire to secureby Letters Patent is: Y

1. As an im roved article of manufacture,

a letter sheet olded atits middle comprising two se arable parts joinedby a weakens I 4 linean one of said arts having rinted on the outer facethereo a letter hea and having written on the outer face thereofa'letter and having written on the inner face thereof a carbon copy of;the reply to said letter and the otherfpart having printed on the outerface thereof the name of the party sending substantiall the originalletter and the commencement of a repl thereto and having written on theouter ace thereof a reply to the original letter and having written onthe inner face thereof a carbon copy of the original letter,

as described.

2. As an improved article of manufacture, a combination record, letterand reply set consisting of two-parts, one of said parts being a singleleaf; andthe other art consist ing-of two separable leaves, fol edtogether and joined by a weakened line and the two leaves so foldedbeing interleaved with the si le leaf, and the outer surface of thefirst lea of the double part bein printed with-a letter headyand havinga blank space, andthe inner surface ofv the second leaf of the ace andthe of the double gart beingl printed with the name and adress of t eperson whose letter head is on double part having a blank s outersurface of the second lea the first leaf and being rinted with a pre- B.C.
